current: lazarus/qt5 SIGSEGV when program exit


slackware-current
qt5 from ~alien/slackbuilds/qt5/pkg64/current/
lazarus 1.8.0 and trunk: qt5-cbinding

any program with qt5 widgets will SIGSEGV when it exit, include simple one form empty project, and whole lazarus ide.
as I remembered, recent 3 or 4 version from ~alien/ has the same issue.

tested on slk 14.2-x86_64, it's good.

already discussed in here:
http://forum.lazarus.freepascal.org/...c,39618.0.html

compared building scripts of glibc and qt5 between slack and arch, can not find anything related.

may any one can help about this?

summary until today:

slackware64-current: qt5 5.9.3
lazarus 1.8/trunk, qt5 binding: SIGSEGV when program exit

it's OK on in ubuntu 17.10 with official QT5 and Qt5Pas, Arch QT 5.10.0
it's OK on slackware64 14.2 QT 5.7.1


discussed at lazarus forum, it looks like related to glibc building.
rebuild glibc without most patches, it's the same.

attached file is backtrace from gdb.

any advise or any tesing is welcome.
